vpnroute | 这个脚本是chnroutes的改进版 使用sh install

I am developing a UWP VPN Plugin. In later stage it should handle OpenVPN. In the first stage I am trying to understand the VpnPlugin to get it work in the simplest possible way. For testing I am using Android's ToyVpn test Server on a Debian VM (https://android.googlesource.com/platform/development/+/master/samples/ToyVpn/server/linux). Unfortunately the VpnPlugin is poor and lousy documented, no Guideline - no Nothing. The Github examples are useless and not working either, even https://github.com/ysc3839/UWPToyVpn gives only Rough orientation. I was able to successfully do the Handshake with the Server who responds with a Parameter chain. When it Comes to start the Connection, an exception is thrown that the device is not connected. I am running out of Options and any help would greatly appreciated.

public sealed class ToyVpnPlugin : IVpnPlugIn { DatagramSocket _datagramSocket; public async void Connect(VpnChannel channel) {
//string parameters = default; string serverPort = "8000"; string secret = "test";
